## Cause

The file $FWDIR/appi/update/appi_status.C file is corrupted.

## Solution

1. Copy "appi_status.C" file under $FWDIR/appi/update/ from another Security Gateway/VS and save it your desktop.

2. Backup the original File on the problematic Security Gateway/VS:

`# cp appi_status.C appi_status.C_Backup`  

3. Replace with the new one under: $FWDIR/appi/update/

(change should be done on the problematic Security Gateway/VS)  

4. Once the file has been replaced, ensure that it is still in unix format with:

<!-- -->

`# dos2unix appi_status.C`

**Notes:** The status and subscription will look all fine. You need to verify from below commands:  
`# cpstat appi -f update_status`  
` # cpstat appi -f subscription_status`  

Debug on RAD process does not point any issue.
